Hi Gustavo Novais.
You are wrong in configure next-hop ipv6 add.
Let say R1 as example If you use route-map out, you should use next hop ipv6 add is the site-local of R1 (FEC0::1) if you use route-map in, you should use next hop ipv6 add is the site-local of R3 (FEC0::3).
You can verify this in the sample Lab 1 of Doit version II preparing for candidates after 1 Jan 2006 of Netmasterclass.
Best Regards

Hi again!
When I do a debug ipv6 packet and deb bgp ipv6
I see that somehow the router R1 is sending packets not to the Serial0/0 but to the FastEthernet (opposite side of R3).
Does any one know of any restriction on using link local with fram-relay?
When I used AGUA addresses directly, all went fine.

Can we see the BGP part of your config?

Yes,
I should have shown sh ipv6 interfaces
R1
Serial0/0 is up, line protocol is up
IPv6 is enabled, link-local address is FE80::20B:FDFF:FE25:13E0
Global unicast address(es):
FEC0::1, subnet is FEC0::/120
R3
Serial0/1 is up, line protocol is up
IPv6 is enabled, link-local address is FE80::20B:46FF:FE86:3900
Global unicast address(es):
FEC0::3, subnet is FEC0::/120
I'm also able to ping one from the other.
Rack1R1#ping FE80::20B:46FF:FE86:3900
Output Interface: Serial0/0
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to FE80::20B:46FF:FE86:3900, timeout is 2

Is the link local address that you are mapping your frame to the same
link-local address of that of the local interface?
Sh ipv6 interface serial 0/0
Probably so, but just have to ask.

Hello
There is an example on Ipv6 documentation on doc CD on which they
exemplify peering between two ipv6 bgp peers using link local addresses.
I'm trying to do it on top of a frame-relay connection. Nevertheless,
the peering never comes up. I've checked my FR maps, I've checked
everything but it still will no work.
I'm asking the group if there's anything wrong I'm doing.
